Leader Harmonious Drive System Co. (688017.SS): 3Q26 snapshot: strong sales, margin trade-offs, and capacity build-out in humanoid robotics

Leader Drive reported 3Q26 results after the close on Friday (30 October), delivering a standout 56% Y/Y sales increase to Rmb242MM, a sharp acceleration from 36% Y/Y in 2Q26 despite a tougher base. The quarter's most notable feature was the rapid sales ramp, which came alongside further GPM compression—down 6.2ppts Y/Y to 33.4%, compared to a 2.5ppts Y/Y decline in 1H26. We attribute this margin trend to the fast-rising contribution of new humanoid robot products, which are scaling up quickly and driving a significant mix shift. Leader Drive is actively expanding in the humanoid segment to capture share, and underlying shipment volumes likely grew even faster than reported sales, potentially above 70% Y/Y. We see this as a positive, as the company is still in a capacity ramp phase, and margins should recover as utilization and scale improve. Management confirmed its ambition for global leadership, supported by a three-year plan to expand capacity 10x to 4MM-6MM units annually. SG&A wa
